name: plutonium-installation description: Installing Plutonium in a Rails application - setup, generators, and configuration

Plutonium Installation

New Rails App (Recommended)

Use the Rails template for a fully configured setup:

Copyrails new myapp -a propshaft -j esbuild -c tailwind \
  -m https://radioactive-labs.github.io/plutonium-core/templates/plutonium.rb

This sets up Rails with Propshaft, esbuild, TailwindCSS, and Plutonium in one command.

Existing Rails App

Option 1: Rails Template

Copybin/rails app:template \
  LOCATION=https://radioactive-labs.github.io/plutonium-core/templates/base.rb

Option 2: Manual Installation

Copy# Add to Gemfile
gem "plutonium"

# Install
bundle install
rails generate pu:core:install

What Gets Generated

After pu:core:install:

Base Classes

ResourceController

Copyclass ResourceController < PlutoniumController
  include Plutonium::Resource::Controller
  # Provides: index, show, new, create, edit, update, destroy
  # Plus: interactive actions, authorization, query handling
end

ResourcePolicy

Copyclass ResourcePolicy < Plutonium::Resource::Policy
  def create?
    true  # Override with your logic
  end

  def read?
    true
  end
end

ResourceDefinition

Copyclass ResourceDefinition < Plutonium::Resource::Definition
  # Add app-wide definition defaults here
end

ResourceRecord

Copyclass ResourceRecord < ApplicationRecord
  self.abstract_class = true
  # Models inherit from this for Plutonium features
end

Authentication Setup

Install Rodauth

Copyrails generate pu:rodauth:install

Create Account Types

Copy# Basic user account
rails generate pu:rodauth:account user

# Admin with 2FA, lockout, audit logging
rails generate pu:rodauth:admin

# Customer with entity association
rails generate pu:rodauth:customer customer

Account Options

Connect Auth to Controllers

Copy# app/controllers/resource_controller.rb
class ResourceController < PlutoniumController
  include Plutonium::Resource::Controller
  include Plutonium::Auth::Rodauth(:user)  # Add this
end

Creating Your First Resource

Copyrails generate pu:res:scaffold Post user:belongs_to title:string content:text
rails db:migrate

Creating a Portal

Copyrails generate pu:pkg:portal admin

Select authentication when prompted:

• Rodauth account - Use existing auth
• Public access - No authentication
• Bring your own - Custom implementation

Mount the Portal

Copy# config/routes.rb
Rails.application.routes.draw do
  mount AdminPortal::Engine, at: "/admin"
end

Connect Resources to Portal

Copyrails generate pu:res:conn Post --dest=admin_portal

Configuration

Copy# config/initializers/plutonium.rb
Plutonium.configure do |config|
  config.load_defaults 1.0

  # Custom assets (optional)
  # config.assets.stylesheet = "custom_stylesheet"
  # config.assets.script = "custom_script"
  # config.assets.logo = "custom_logo.png"
end

Package System

Packages are loaded from config/packages.rb:

CopyDir.glob(File.expand_path("../packages/**/lib/engine.rb", __dir__)) { |package| load package }

Create packages in packages/ directory:

• Feature packages - Business logic (rails g pu:pkg:package blogging)
• Portal packages - Web interfaces (rails g pu:pkg:portal admin)

Post-Installation Checklist

1. Install core

   Copyrails generate pu:core:install
   

2. Setup authentication (if needed)

   Copyrails generate pu:rodauth:install
   rails generate pu:rodauth:account user
   

3. Create a portal

   Copyrails generate pu:pkg:portal admin
   

4. Create resources

   Copyrails generate pu:res:scaffold Post title:string content:text
   

5. Connect resources to portal

   Copyrails generate pu:res:conn Post --dest=admin_portal
   

6. Run migrations

   Copyrails db:migrate
   

7. Mount portal (add to config/routes.rb)

   Copymount AdminPortal::Engine, at: "/admin"
   

8. Start server

   Copyrails server
   

Converting Existing Models

For models that already exist in your app:

1. Include the module:

   Copyclass Post < ApplicationRecord
     include Plutonium::Resource::Record
   end
   

2. Generate supporting files (skips model/migration):

   Copyrails g pu:res:scaffold Post
   

3. Connect to portal:

   Copyrails g pu:res:conn Post --dest=admin_portal
